        • Q:

          I'm looking for a replacement bulb for an old fixture. The old bulb has no markings, is 17.2" from end of cap to end of cap, is 1" in diameter, and I don't know how long it is from end of pins to end of pins (quite possibly 18"). Does the 15 Watt, 18 Inch T8 Cool White Fluorescent Bulb by Philips fit my fixture?

            A:

            Lamp measurements are taken from pin to pin. It appears that the Philips 18" fluorescent uses 15 watts, so this looks like it would be your bulb. The 1" diameter tells us that this is a T8 lamp.
